Specification of Letters Patent.

Application filed March 14, 1912. Serial No. 683,759.

, tion, like reference characters on the drawings indicating like partsin the several figures.

This invention relates to shoe supports and has for its object toprovide a support having improved facilities for presenting the shoeheld by it in position to be operated upon.

The invention is herein embodied in a support for holding a lasted andsoled shoe in position for the shank to be beaten at each lateral edgedownwardly upon the bottom of the last which is at such times within theshoe, the purpose of the operation being to conform the shank of theshoe bottom to the transverse curvature of the last bottom and tocompact the materials of the shoe bottom so that in appearance they willpresent a minimum of thickness. The beating machine illustrated is anadaptation of the machine shown in United States Letters Patent No.768,560 granted August 23, 190% on my application and in which theoperation of the machine is dependent upon the maintenance of continuouscontact between the work and the beating tool. One of the problems to beconsidered in the contemplated use of a beating machine is the reductionof the transmission of vibration through the shoe and support to thetreadle upon which the operator must maintain his foot.

One of the features of this invention is found in the construction andarrangement of the connections between the treadle and the jack spindle.The main features of the curvature of the shoe bottom in the shank ateither edge and-another valuable charac teristic of the shoe holder isthe provision for the heel clasp and the toe clasp each to turnindependently about substantially identical axes that extend lengthwiseof the shoe Patented Dec.22,11914t.

for adaptation of the clasps to the shape of the shoe. These and otherfeatures of the invention will now be described in connection with thedrawings and then be particularly pointed out in the claims.

Figure l is a side elevation of a machine in which this invention isembodied; and Fig. 1 is a detail of the treadle connection; Fig. 2 is aperspective view of the shoe holder; Fig. 3 is a vertical longitudinalsection of the heel clasp; Fig. 4 is a similar section of the toe clasp.

The column or frame has bearings for the jack spindle 2 the lower end ofwhich is sustained by a toggle 4t, 5 The member 5 being pivoted to thecolumn at 6 and having a horizontal arm 8 is in effect a bell crank orspindle lifting rocker. Underlying the arm 8 is the arm 9 of a rockshaft 11 the other arm 10 of which overlies the rear arm of treadle 12.A spring 15 approximately balances the weight of the jack while a stop13 limits the extent to which the spindle may be pressed down when ashoe on its last is placed in the holder. The described leverage betweenthe treadle and the spindle affords ample advantage for holding the shoeup to the pounding tool 100 which is rapidly reciprocated by impulsesfrom a rotary actuator as described in United States Letters Patent No.768,560, and at the same time said leverage connections absorb thevibrations of the shoe holder sufficiently so that there is not anobjectionable motion of the treadle upon which the operator must holdhis foot while a shoe is being pounded. A spring 16 is confined on thespindle between collars 17, 18, the latter of which is adjustable tovary the compression of the spring. Upon the upper end of the spindleshoe holder upon the table within the limits of the hole in the table.The float has roll- .ers 26, 27, 26 between which is confined and guidedthe arc-shaped foot 30 of the shoe holder, the same being curvedsubstantially parallel with the curvature of the shank, see Fig. l, of astandard shape of last so that the beating point on the shank ismaintained in approximately the same vertical relation to tool 100 asthe beating progresses along the shank.

The heel clasp post 32 is secured upon one end of the foot 30 and thetoe clasp post l0 upon the other end, each post being made adjustablefor the length of the shoe. lhe heel clasp comprises a back plate 34having .a horizontal stem 35 which is confined but free to turn in asocket in the post. On its lower edge the back plate is formed as an arecurved about the stem and rests on a similarly curved shelf formed onthe front side of the post to assist in sustaining the weight of theheel clasp and the shoe so that the stem 35 can turn freely. Wing blocksor plates 36 are confined in a transverse guideway in the front face ofthe plate by acap 38. The forwardly extending padded wings of theseblocks 36, which are downwardly and inwardly inclined to form a seat forthe heel constitute the heel sustaining members of the shoe holder andthey are adjustable from and toward each other by the screw rod 39 forwide and narrow shoes.

The toe post 620 has on the rear side an arc-shaped guide rib curvedabout an flXlS substantially corresponding with the stem 35 and on whichslides a block 42 in which is clamped for vertical adjustment the stemof a toe rest -15 that has limited turning movement on its stem about atransverse pivot 44. The toe post also pivotally supports at 48 the toeabutment 50 which has a thickly padded back face and is movable in adlrection to engage over the toe end of a'shoe and clamp it down uponthe toe rest with suliicient security to retain the shoe firmly in theholder- A handle lever 52 is pivoted on the front side of the abutmentby which to lift it into clamping engagement with the toe of the shoeand a spring pressed pawl on the abutment is arranged to engage ratchetteeth in the toe block to lock the abutment in operative position. Thehead of the pawl is located under the handle lever 52, downward pressureupon winch first lifts the point of the pawl and then swings theabutment to free the shoe. The weight of the handle'lever holds thepoint of the pawl normally raised but the pivot for the pawl is solocated that after the abutment has been clamped down upon the toe bythe use of the lever 52 the pawl spring causes the pawl to engage theratchet teeth and the pressure caused by the reaction of the workmaintains the engagement after the handle has been released. A spring 56returns the abutment to an upraised position after the shoe has beenremoved. The location oi the pivotal connection between the abutment 50and the toe post 40 is such that the abutment can clamp shoes of severalsizes without resorting to adjustment of the toe post or the heel poston the foot 30.

In the use contemplated in the drawings a lasted and soled shoe, withthe last in it, will be dropped into the heel clasp, pushed back, andthen pressed down upon the toe rest, the abutment being swung aside forthis latter purpose. The handle 52 will then be lifted to clamp theabutment against the toe of the shoe, the direction of movement of theabutment serving to clamp the shoe backwardly into the heel clasp aswell as downwardly upon the toe rest and the pawl 54 will lock theabutment while the handle is upraiscd. While the shoe is being appliedto the holder the holder will have occupied a position on table 20 mostemote from the tool 100. The holder will now be moved across toward thetool and the treadle pressed down to lift the shoe into the field ofaction of the tool 100 and maintain it there. The operator then tips theshoe by a movement of the foot 30 in its guide 26, 27, 26 and slides theholder on table 20 to present one side of the shank to the tool and thenturns the holder around on the table and similarly presents the otherside of the shank. Downward pressure on handle 52 will release pawl 54:and tip back the abutment to allow the shoe to be removed. Theconnections between the spindle 2 and the treadle 12 preventobjectionable jarring of the treadle by reason of the vibration of thetool.
